JOHN NAGEL, OF FULTON, l\lISSOURl.

KNIFE.

SPECIFICATION forming part of Letters Patent No.3l0,606, dated January 13, 1885 (No model.)

To all whom it may concern.-

Be it known that 1, JOHN NAGEL, a native of Switzerland, who have declared my intention of becoming a citizen of the United States, residing at Fulton, in the county of Gallaway and State of Missouri, have invented certain new and useful Improvements in Knives; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

. My invention relates to knives intended especially for butchers use; and it consists in the novel construction, hereinafter more fully described and claimed.

In the drawings, Figure 1. is a side view of the knife; Fig. 2, an edge view, enlarged, of the handle A. Figs. 3 and 4 are detail views, all of which will be described.

The handle A has its head A made wider than its hand portion A-, and thejuncture of such hand portion and head forms shoulders a a on opposite sides, which prevent the hand from slipping down off portion A over the head and onto the blade secured to said head, as will be described. The head A. is bifurcated by slot B, which extends the full. width of the head, and is fitted to receive the blade and to permit the adjustment thereof, hereinafter more fully described. The screw 0 extends from one arm of the head across slot B and through the other arm, and extends sufficient] y far beyond the latter to receive the clamping and retaining nut 0, preferably formed with thumb-wings, so it may be operated by hand. This nut is turned down against the face of the head A, and the screw 0 has an angular portion, 0", near its head,which fits a corresponding opening in the head A, so the said screw is held from rotation in the operation of the device. This screw 0 is arranged preferably equidistant from the opposite edges ofthe head A, for the purposes more'fully hereinafter explained. A series of perforations, D, is formed transversely through the head, and are arranged preferably in the are of a'circle struck from the opening through which the pivot-screw C is passed. A link, E, is journaled at one end on screw 0, and is retained therein by nul (1, turned downagainst it, as shown in Fig. 2. This link may be swung on the screw as a pivot when nut O is loosened, and it has near its swinging end the retaining pin or projection F, depending and arranged in position to engage any one of the series 01' holes D in the operation of the device. The blade G is provided with a longitudinal slot, 9, and has formed through it, near its ends, openings 9, arranged in line with slot 9, for the purposes presently described. Oneextrem ity or point, 9", of this blade may be rounded, so as to be useful in skinning cattle, sheep, 820., or steak-cutting, and its other end, 9, be pointed, to adapt it to the purposes of sticking in slaughtering pigs, &c., or the opposite ends might be otherwise formed to meet the wishes of the maker. It will be noticed the slot 9 is formed back from the front edge of the blade a distance equal, or approximately so, the distance from the screw 0 to the sides of the head of the handle, so that when said'blade is secured to the handle and adjusted in line there with its cuttingedge will lie about flush with the sides of the head, as will be understood from the dotted lines, Fig. 1.

In operation the blade is placed in the slot B and the pivot screw or pin 0 inserted through the slot 9. The blade is thus secured to the handle. If it is desired to chop meat, the blade may be adjusted to the right'angled position shown in Fig. 1.

hen it is desired to use the knife for cut-- ting steaks or similar purposes, it may be adj usted to the dotted position indicated in Fig. 1, in which position it may be held by the pin F, operating through one of the holes D and the slot 9, or one of the holes g, as described. It will be understood that the blade may be turned to any angle between the full and dot ted position shown in Fig. 1, and be secured at such angle, or it maybe inverted, so that its edge will be toward the operator, so that the knife may be used for making drawing cuts, as is frequently desirable.

I prefer in practice to use the link E and secure the pin F thereto; but it is manifest such pin might be used detached from the link and screw-threaded through the openings D; but by the link it is securely held and may be easily and quickly adjusted from one to the others of the perforations, as will be appreci stantially as set forth.

2. The combination of the handle having its head slotted longitudinally, the blade placed in said slot and provided with a slot or opening, and the clamping and pivot screw turned through the handle and blade, and adapted to clamp the latter in any desired position, substantially as set forth.

3. The combination of the handle having a slot, 13, and pivot-opening and perforations I), of the blade secured in said slot, and provided with a slot, 9, and the pivot-screw and retain ing-pin, substantially as set forth.

4. The combination, with the handle having slot B and transverse pivot-opening and openings-D, arranged in curved series, and the blade having a slot, 9, and openings 9, arranged in line with said slot, of the pivot-pin and the retaining-pin, all arranged and operating substantially as and for the purposes specified.

5. The combination, with the handle having its head slotted longitudinally, and the blade inserted midway its ends in said slot, and having its ends projected on opposite sides of and adjustable to any suitable angle relative to the handle, of devices whereby said blade may be held at any angle desired, substantially as set forth.

6. The combination of the handle provided with a curved series of apertures, D, and the blade pivoted at O to said handle, and adjustable on said pivot, and provided with an opening arranged to register with openings D, the link and the retaining-pin depending therefrom, substantially as set forth.

In testimony whereof I affix my signature in a presence of two witnesses.

JOHN NAGEL.
